If a solution, contained in a 1cm cuvette, has an absorbance value of of 0.865 A.U, and concentration value of 2mM. What is the value regarding the molar extinction coeffient?

Firstly, using Beer-Lambert's equation. It is noted, that absorption is equal to the molar extinction coefficient, multiplied by the path length of light, multiplied by the concentration of the solution.Ther...

why do metallically bonded structures conduct electricity

In order for metals to bond they need to loose electrons to ensure that they have a full outer shell and become positively charged. The positive cations (metal ions) are attracted to the negatively charged e...
